Stainless steel three-drum dryer

Structural composition:

• Drum part:

It is composed of three stainless steel cylinders of different diameters nested concentrically. This is the core component of the equipment. Stainless steel has good corrosion resistance, high temperature resistance and strength, which can ensure that the equipment is not easy to rust or deform during long-term operation, and is suitable for a variety of harsh working environments.

• Transmission device:

Including motor, reducer, gear, roller, etc. The motor provides power, and drives the drum to rotate through transmission parts such as reducer and gear to ensure that the material is constantly rolling and moving in the drum to achieve uniform heating.

• Feeding device:

Located at one end of the dryer, it is responsible for conveying the material to be dried into the dryer. Its design must ensure that the material can enter the drum stably and evenly to avoid blockage or uneven feeding.

• Discharging device:

At the other end of the dryer, it is used to discharge the dried material. The discharging device has good sealing to prevent hot gas leakage and dust overflow.

• Heat source system:

Provides heat for the dryer. Common heat sources include coal, natural gas, biomass pellets, electric heating, etc. The heat source system needs to be reasonably configured according to actual needs to ensure a stable supply of heat.

• Dust removal system:

Used to collect and process dust generated during the drying process to reduce pollution to the environment. The performance of the dust removal system is crucial to the environmental protection effect of the equipment.

Advantages and characteristics:

High drying efficiency:

• Sufficient heat exchange:

The three-drum structure greatly increases the contact area between the material and the hot air flow. After the material is initially heated in the inner drum, it enters the middle drum and the outer drum. The heat exchange process is more sufficient, and the moisture in the material can be quickly and effectively removed. Compared with a single-drum dryer, its drying efficiency can be increased by more than 30% - 50%.

• Unique travel mode:

The material has a unique travel mode in the drum, such as spiral travel in the inner drum and two steps forward and one step back in the middle drum, which prolongs the residence time and drying time of the material in the drum and ensures the drying effect.

Good material drying quality:

• Drying evenly:

Reasonable cylinder structure and lifting plate design enable the material to be evenly dispersed and turned in the dryer, avoiding material accumulation and uneven drying. The moisture content of the dried material is uniform and can reach below 1% - 0.5%.

• High material quality:

Due to the uniform distribution of temperature and heat during the drying process, the material will not deteriorate, discolor, agglomerate, etc. due to local overheating, which well guarantees the quality of the material and is suitable for materials with high drying quality requirements.

Excellent equipment performance:

• Strong corrosion resistance:

The cylinder and other key components are made of stainless steel, which has excellent corrosion resistance and can resist the erosion of various corrosive materials and harsh environments, greatly extending the service life of the equipment and reducing the maintenance cost of the equipment.

• High strength and good stability:

The stainless steel material has high strength and can withstand large material weight and operating load, ensuring the stability and reliability of the equipment during operation. At the same time, the transmission device and other components of the equipment use high-quality parts to further improve the overall performance of the equipment.

• Good thermal insulation performance:

The design of the three-cylinder structure makes the equipment have good thermal insulation performance. The outer cylinder plays a role in thermal insulation for the inner cylinder and the middle cylinder, reducing heat loss and improving energy utilization.

Environmental protection and energy saving:

• Significant energy saving effect:

Efficient heat exchange and good thermal insulation performance make the energy consumption of the equipment lower. Compared with traditional drying equipment, the energy saving effect is obvious. At the same time, the appropriate heat source can be selected according to actual needs to further reduce energy costs.

• Good environmental performance:

Equipped with an advanced dust removal system, it can effectively collect and treat dust and exhaust gas generated during the drying process, reduce pollution to the environment, and meet environmental protection requirements.

Convenient operation and maintenance:

• High degree of automation:

The equipment is usually equipped with an automatic control system, which can achieve precise control of the drying process, including the adjustment of parameters such as temperature, speed, and feed amount. The operation is simple and convenient, reducing the difficulty and labor intensity of manual operation.

• Low maintenance cost:

The structure of the equipment is relatively simple, and daily maintenance work is relatively easy. The main maintenance work includes regular inspection of the equipment's operating status, lubrication of parts, cleaning of the cylinder, etc., and the maintenance cost is low.
